| Abstract | ||
| This experiment was carried out during the two successive seasons of 2019 and 2020, to evaluate the effect of PVP and PVA as stabilizers and capping agents to control the size of the potassium mono hydrogen phosphate (potassium phosphate) and zinc oxide nanoparticles produced by gamma irradiation. HRTEM measurement reveals the formation of potassium mono hydrogen phosphate and zinc oxide nanoparticles within the polymeric networks of PVP and PVA, with mean sizes of 6.3 nm and 33 nm, respectively. Fourier transform infrared (FT-IR) spectroscopy revealed the structure formation of PVP/ potassium mono hydrogen phosphate nanoparticles and PVA/ zinc oxide nanoparticles. The formation of potassium mono hydrogen phosphate and zinc oxide nanoparticles is proved by UV–vis spectroscopy measurements, which reveal distinctive absorption peaks. The agriculture study during the two successive seasons of 2019 and 2020, under El Nuberia Region, Beheira Governorate show that potato plants cv.Spunta sprayed with 8 ml / l of potassium phosphate and 9 ml / l of zinc oxide nano composite gave the tallest plant, highest fresh and dry plant haulm and number of stems per plant. As for potato yield, both previous concentrations scored the highest number of tubers per plant, average tuber weight and total yield per feddan, as well as chemical constituents of tubers such as specific gravity, dry matter percentage, starch, phosphorus and potassium percentage as well as zinc concentration. | ||
